Rule out obturator nerve entrapment. Diagnosis is by EMG. It is common with those who bicycle.
I'm so sorry you are in pain... What else has your doctor said or recommended? Have you had any tests done? I have heard of a lot of gynos basically ignoring some patients and just either putting them on something or upping the dosage and sending them out the door, I think you should at the least get a second opinion. You should never be in pain down there like at unless there's a reason, I would bring up high concern to your regular family doctor and this gyno, If she doesn't do anything else to look into it then please go to another high rated gyno in your area.
